Plateau Uranium Drills Unique and Large Lithium Target in Peru:
Plateau Uranium Inc. (TSXV: PLU) is pursuing a drilling campaign to define what it sees as potentially one of the world’s largest non-brine lithium deposits in the Falchani target on its 100% owned Macusani lithium-uranium property in Puno, southern Peru.
The Toronto-based company commenced drilling its +2 sq. km Falchani target in October 2017, shortly after signing a first access agreement with the Chaccaconiza Community. The assays showed uranium down to 50 metres below surface level with twice the average grade of the company’s preliminary economic assessment (PEA). However, the company says it was even more encouraged by a lithium intersection roughly 80 metres to depth and open for expansion at widths up to 60 metres, grading an average 3,500 parts per million (ppm) lithium. As a result, Plateau's focus for the first half of 2018 is to continue drilling and have an updated National Instrument 43-101 compliant lithium resource estimate by May 2018. Drilling so far has focused on less than 15% of the company's total land package of 910 sq. km. It's one heck of a lithium deposit with a real cherry on the top of a very nice uranium project, quite separate from the lithium, it's not intermingled. It's two separate deposits with both metals able to be mined separately.
The company currently has three drill rigs mobilized at Falchani and will drill from 12 platforms. The holes will be 200-250 metres deep. The ellipsoid for the lithium rocks is so large, Plateau doesn't have to space its drill holes less than 150 to 200 metres apart.
Unlike most lithium deposits which are found in brine or pegmatite, Plateau's lithium is in volcanic rocks. As a result, the company says the lithium is easy to extract. The PEA includes a resource estimate of 95.2 million measured and indicated tonnes grading 0.546 lbs per tonne uranium for 51.9 million lbs uranium.
Plateau would go on to put out a NI 43-101 compliant lithium resource in 2016 of 52 million indicated tonnes grading 0.13% lithium for 67,000 tonnes lithium oxide and 88 million inferred tonnes grading 0.12% lithium for 109,000 tonnes lithium oxide contained entirely within the uranium deposits considered in the PEA.
While Plateau still envisions itself as a future uranium producer, it sees lithium as the more important element at this moment.
